Concrete filled tube (CFT) columns have been used as primary axial load-carrying members in high-rise building especially in seismic zones. The structural member has become popular as it has a number of distinct advantages over an equivalent steel, reinforced concrete, or steel-reinforce concrete structural member. This paper is intended to presents numerical modeling of elliptical concrete-fil...
INTRODUCTION The total hip arthroplasty (THA) as part of acute fracture management is used for acetabular fractures in elderly patients. Our objective was to assess the stability of osteosynthesis performed using 2 different techniques in combination with THA in an experimental model. MATERIALS AND METHODS We conducted 20 experiments using the left-side hemipelves composite bone models. There...
There is a growing interest in the relationship between occlusion and posture because of a greater incidence of neck and trunk pain in patients with occlusal dysfunction. The study was designed to verify whether an alteration of the spinal column alignment may be experimentally induced in rats as a consequence of altering dental occlusion and also to investigate whether the spinal column underw...
In this paper, the Two-Scale computation Method (TSM) is presented for the mechanics parameters of composite materials with small periodic configuration, including stiffness parameters and strength parameters. First the major formulation of the Two-Scale Asymptotic expressions (TSA) for composite materials with periodic configuration is briefly given. And then the two-scale computation (TSM) fo...
The assessment of response of composite seismic force resisting systems requires accurate nonlinear formulations for the composite members. In this work, reporting the first phase of a NEES project, a three-dimensional distributed plasticity formulation is presented for both circular and rectangular composite concrete-filled steel tubes (CFTs) that includes new constitutive models for the concr...
